Valve ya butterflyndi mtundu wa valavu yomwe imagwiritsa ntchito membala wotsegulira ndi kutseka kwa disc kuti abwezere pafupifupi 90 ° kuti atsegule, kutseka kapena kusintha kayendedwe ka sing'anga.Valve ya butterfly sikuti imakhala ndi mawonekedwe osavuta, kukula kochepa, kulemera kochepa, kugwiritsira ntchito zinthu zochepa, kukula kwazing'ono, makina oyendetsa galimoto, ntchito yosavuta komanso yofulumira, komanso imakhala ndi ntchito yabwino yoyendetsera kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe kake.Ndi imodzi mwa mitundu ya valve yomwe ikukula mofulumira kwambiri m'zaka khumi zapitazi.Ma valve a butterfly amagwiritsidwa ntchito kwambiri m'mafakitale ambiri.Zosiyanasiyana ndi kuchuluka kwa ntchito yake zikukulirakulirabe, ndipo ikukula mpaka kutentha kwambiri, kuthamanga kwambiri, m'mimba mwake yayikulu, kusindikiza kwakukulu, moyo wautali, mawonekedwe abwino kwambiri, komanso magwiridwe antchito ambiri a valve imodzi.Kudalirika kwake ndi zizindikiro zina zogwirira ntchito zafika pamtunda wapamwamba.
Pogwiritsa ntchito mphira wosamva mankhwala pa valavu ya agulugufe, magwiridwe antchito a gulugufe asintha.Popeza mphira wopangidwa ali ndi mawonekedwe a kukana dzimbiri, kukana kukokoloka, kukhazikika kwa mawonekedwe, kulimba mtima, kupanga kosavuta, komanso mtengo wotsika, mphira wopanga wokhala ndi zinthu zosiyanasiyana amatha kusankhidwa malinga ndi zofunikira zosiyanasiyana zogwiritsira ntchitovalavu butterfly.
Chifukwa polytetrafluoroethylene (PTFE) imakhala ndi kukana kwamphamvu kwa dzimbiri, kugwira ntchito mokhazikika, kosavuta kukalamba, kugundana kocheperako, kosavuta kupanga, komanso kukula kwake kokhazikika, ndipo mawonekedwe ake onse amatha kupitilizidwa podzaza ndi kuwonjezera zida zoyenera, zomwe zimapangitsa kuti pakhale mphamvu komanso mphamvu. kukangana.The gulugufe valavu kusindikiza zinthu ndi m'munsi coefficient kugonjetsa malire a mphira kupanga, kotero zipangizo polima akuimiridwa ndi PTFE ndi kudzazidwa ndi kusinthidwa zipangizo akhala ankagwiritsa ntchito mu valavu agulugufe, kuti ntchito mavavu agulugufe bwino.Valve yagulugufe yokhala ndi kutentha kwakukulu komanso kupanikizika, kusindikiza kodalirika komanso moyo wautali wautumiki wapangidwa.
Pofuna kukwaniritsa zofunikira za kutentha kwakukulu ndi kotsika, kukokoloka kwamphamvu, moyo wautali ndi ntchito zina zamakampani,zitsulo zosindikizidwa za butterfly valveszapangidwa kwambiri.Ndi kugwiritsa ntchito kukana kutentha kwambiri, kukana kutentha kwapansi, kukana kwa dzimbiri, kukana kukokoloka kwamphamvu, ndi zida zamphamvu za aloyi mu mavavu agulugufe, mavavu agulugufe osindikizidwa zitsulo akhala akugwiritsidwa ntchito kwambiri m'mafakitale monga kutentha kwapamwamba ndi kutsika, kolimba. kukokoloka, ndi moyo wautali.
Vavu yagulugufe ikatsegulidwa kwathunthu, imakhala ndi mphamvu yocheperako.Pamene kutsegula kuli pakati pa 15 ° ndi 70 °, kuwongolera kothamanga kungathe kuchitidwa, kotero m'munda wa kusintha kwakukulu, kugwiritsa ntchito ma valve agulugufe kumakhala kofala kwambiri.
Chifukwa mayendedwe a gulugufe mbale akupukuta, mavavu agulugufe ambiri angagwiritsidwe ntchito TV ndi inaimitsidwa olimba particles.Kutengera mphamvu ya chisindikizocho, itha kugwiritsidwanso ntchito ngati ufa ndi granular media.
Ma valve a butterfly ndi oyenera kuwongolera kayendedwe kake.Chifukwa kuthamanga kutayika kwa valavu ya gulugufe mu chitoliro ndi yaikulu, yomwe ili pafupi katatuvalve pachipata, posankha valavu ya butterfly, chikoka cha kutayika kwa payipi ya payipi chiyenera kuganiziridwa bwino, ndipo mphamvu ya gulugufe kuti ipirire kupanikizika kwa sing'anga ya payipi iyeneranso kuganiziridwa ikatsekedwa.Kuphatikiza apo, kuchepa kwa kutentha kwa zinthu zapampando za elastomeric pamatenthedwe okwera kuyeneranso kuganiziridwa.
Mavavu agulugufe ali ndi utali wocheperako komanso kutalika konse, kutsegulira mwachangu ndi kutseka, komanso mawonekedwe abwino owongolera madzimadzi.Kapangidwe ka valavu ya butterfly ndi yabwino kwambiri popanga valavu yayikulu.Pamene valavu ya butterfly ikufunika kuti igwiritsidwe ntchito poyendetsa kayendetsedwe kake, chinthu chofunika kwambiri ndikusankha molondola ndondomeko ndi mtundu wa valavu ya butterfly kuti igwire bwino ntchito.
Nthawi zambiri, pakuwongolera, kuyendetsa bwino komanso matope, pamafunika kukhala ndi kutalika kwaufupi, kutsegulira ndi kutseka mwachangu, kutsika kwapang'onopang'ono (kusiyana kwapang'onopang'ono), ndi valve ya butterfly ikulimbikitsidwa.Valavu ya butterfly ingagwiritsidwe ntchito posintha magawo awiri, njira yochepetsera m'mimba mwake, phokoso lochepa, cavitation ndi vaporization, kutayikira pang'ono kumlengalenga, ndi sing'anga yowononga.Valve ya butterfly imatha kugwiritsidwanso ntchito posinthira kugwedeza pansi pamikhalidwe yapadera yogwirira ntchito, kapena kugwiritsidwa ntchito pogwira ntchito monga kusindikiza mwamphamvu, kuvala kwambiri, kutentha pang'ono (cryogenic), ndi zina zambiri.
